Configuring Data and Voice
46
Z-Edge 64 Configuration Guide
For example, if the interface is carrying four voice calls, determine the PCR
as follows:
4 x 200 = 800 CPS
Creating a traffic descriptor
The following example creates a new atm-traf-descr with an index value
of 2:
zSH> new atm-traf-descr 2
index can be any value
Please provide the following: [q]uit.
td_type: -------------> {atmNoClpNoScr}:
td_param1: -----------> {0}: 800
PCR for the interface
td_param2: -----------> {0}:
td_param3: -----------> {0}:
td_param4: -----------> {0}:
td_param5: -----------> {0}:
td_service_category: -> {ubr}: cbr
for voice
td_frame_discard: --------> {true}:
cac-divider: -------------> {1}:
usage-parameter-control: -> {true}:

Save new record? [s]ave, [c]hange or [q]uit: s
New record saved.
Creating a new ATM Virtual Circuit Link (VCL)
Create a new atm-vcl record specifically for voice.
Note:
Each new VCL created must have a unique VPI/VCI pair to
specify separate virtual channels. Create a new atm-vcl profile on the
WAN interface to specify voice traffic (AAL2) over a different VPI/
VCI pair than the VPI/VCI values used in the system default atm-vcl
profile.
Modify the following parameters in the atm-vcl profile to enable voice
communications:
Parameter
Description
vci
The VCI for this VCL. This must
match the remote end of the
connection.
admin_status
Administrative status of the link.
Values:
up
down
Default: down
